Goodies arrived...
First was the stuff from Airparts...3 x 4 sheet of .032 3003 to start fabbing new C Channel...and some 5/32 cleco's...my 1/8 clecos won't hold in the old holes so it's kinda tough hanging the old corner c channels in place...($40 of stuff, $22 in shipping)

I also managed to make it to the local steel supplier for a 20' chunk of 2 x 4 x .125 tube stock...my replacement crossmembers are now ready...($84)

UPS stopped today and dropped of a gallon of Eastwood rust stuff...($130?)
